Rhizosphere Interactions on Soil Carbon Cycle under Stress Environments
Rhizosphere interactions play a vital role in regulating the soil carbon cycle, especially under stress environments such as drought, salinity, and nutrient limitations. The rhizosphere, a narrow zone around plant roots influenced by root exudates and microbial activity, acts as a dynamic hotspot for carbon input and transformation. Under stress, plants often alter their root exudation patterns, releasing different types of organic compounds that directly influence microbial communities and soil enzymatic processes. These changes can either accelerate or slow down carbon decomposition, stabilization, and sequestration. Stress environments also shift microbial composition, favoring stress-tolerant species that may enhance or reduce soil carbon storage potential. Understanding these complex plant–microbe–soil interactions under stress is critical for predicting carbon cycling dynamics and developing sustainable strategies for soil health, climate resilience, and carbon management i...
